Filter by:The main purpose of this study is to evaluate the effects of an acute dose of dietary nitrate in the form of beetroot juice on skeletal muscle blood flow in response to dynamic knee extension exercise in healthy older adults. All subjects will receive active (rich in dietary nitrate) or placebo (devoid of nitrate) supplementation.
Extended bouts of periodic mastication and intermittent energy restriction (IER) may improve cognitive performance in the context of adult hippocampal neurogenesis in an ageing population. A randomised controlled parallel design trial will determine the impact of a 3 month IER diet (2 consecutive days of very low calorie diet and 5 days of normal eating) and a mastication intervention (1 piece of gum chewed for 10 minutes 3 times a day) in comparison to a control on neurogenesis-associated cognitive measures and circulating levels of the anti-ageing protein Klotho.
Human aging is characterized by a progressive deterioration of multiple physiologic systems, with marked decreases in skeletal muscle mass, muscle strength, physical function and quality of life beginning in the sixth decade in life. These deleterious modifications have a significant impact upon mobility and ability to undertake daily living activities in elderly people. If we consider that, according to current projections, the proportion of the European population over 65 years will increase from 17% in 2010 to 30% in 2060 and that physical activity participation rates for older adults (>60 years) remain low, with only 16% meeting the recommendations of the American College of Sports Medicine Guidelines (11% for resistance training), we need to understand what type of training (strategy) can be the most effective for reverse physical impairments, and not only that, but which one obtains greater adherence and self-perception for contribute a healthier, active and more independent elderly population in the future. Thus, the purpose of this study is to investigate the effects of 20-week slow-speed traditional resistance training, high-speed resistance training and multicomponent training program with variable resistance (elastic bands) on molecular, body composition, neuromuscular, physical function and quality of life variables in older adults. This research also aims to evaluate if this novel types of training intervention (using variable resistances such as elastic bands in all the training programs and measure the intensity with the OMNI-RES perceived exertion specific for older adults) is feasible in this population, through analysis of adherence, intervention fidelity and self-perception reported.
An accumulating body of research indicates that activities such as exercise, active cognitive and social engagement, good sleep hygiene, stress reduction and proper nutrition are associated with the maintenance of cognitive health. Emerging data also suggests that healthy lifestyle behaviors may promote brain plasticity. Despite nationwide efforts to raise public awareness about brain health, there remains a gap concerning how to best promote behavioral change and help at-risk middle-aged and older adults adopt effective, evidence-based brain health behaviors into their everyday lives to maximize cognitive health. The objective of this study is to evaluate the efficacy of a 7-week group brain fitness intervention (B-Fit) for increasing preventative brain health behaviors and enhancing cognitive health in participants at-risk for cognitive impairment. We will also examine mechanisms of action of the B-Fit intervention through tracking of behavioral responses in the real-world environment using wearable sensors.
This study will test whether chronic metformin administration will improve longevity of the cell, improves its machinery by reducing aging-related biochemical parameters and thereby improving physical performance, as measured by short physical performance battery test.
This is a multi-centre, randomized controlled trial comparing operative and non operative treatment for displaced patella fractures in elderly, low-demand patients.
The present study aimed at investigating the effects of two different resistance training protocols — nonperiodized (NP) and daily undulating periodization (DUP) — on hemodynamic, morphofunctional and cognitive parameters of robust older women. Methods: Forty-two older women were randomized allocated into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic, morphofunctional and cognitive parameters occurred before, during and after six months. The exercise groups performed the program of exercise twice a week over 22 weeks. In NP, the two weekly sessions were based on 3 sets of 8-10 repetitions at a difficult intensity. However, in DUP, a power exercise session based on 3 sets of 8-10 repetitions at a moderate intensity was added in the first session of the week.
The aim of the study was to analyze the effectiveness of a comprehensive cognitive remediation program (REHACOP) in the non demented elderly, obtaining improvements in cognition and functional skills. It was a longitudinal randomized controlled trial with three assessments: basal, post-treatment, and 12-month follow-up. Recruitment and enrollment were conducted between September 2012 and November 2016. All participants underwent a clinical interview and an extensive neuropsychological battery. Patients were randomized in an experimental and a control group. The groups were formed by a maximum of eight participants run by an experienced therapist. The experimental group received cognitive remediation for 3 months, 3 times per week, 60 minutes per session. The control group consisted of occupational group activities (reading the newspaper, drawing, singing or doing crafts) with the same frequency as the experimental group. Post-treatment assessment was carried out within the first week after completing the intervention. Finally, longitudinal follow-up at 12 months with neuropsychological assessments will be performed. Objective: To examine the efficacy of a comprehensive cognitive training program (REHACOP) to improve cognition, clinical symptoms and functional disability for the elderly.
Aging is associated with significant declines in muscle mass, strength, and physical performance, all of which lead to disability, loss of independence, and adverse clinical outcomes. Obesity exacerbates these age-related declines in function and is associated with poorer clinical outcomes and quality of life. Weight loss can also worsen age-related loss of muscle mass and decrease bone mineral density. The overall goals of this study are to determine if the short-term functional benefits of intentional weight loss are sustained long-term, and to examine the long-term benefits and risks of weight loss.
